    Here's kind of a funny solution:

    main = interact $ filter (/= '-')

    Haskell

    -- Enter your code here. Read input from STDIN. Print output to STDOUT

f arr = [abs x | x <- arr]-- Complete this function here

-- This section handles the Input/Output and can be used as it is. Do not modify it.
main = do
   inputdata <- getContents
   mapM_ putStrLn $ map show $ f $ map (read :: String -> Int) $ lines inputdata

    Full solution including IO-handling in F#:

    Seq.initInfinite (fun _->System.Console.ReadLine())
|> Seq.takeWhile ((<>) null)
|> Seq.map (int>>abs)
|> Seq.iter(printfn "%d")
